O-SRINK materials are ideal for any applications where weight savings associated with MI cable shielding is of paramount importance. The product consists of polyolefin heat shrinkable tubing, connector boots, and transition pieces that are coated with homerics unique silver filled coating system. The O-SRINK cable shielding system allows for relatively easy assembly of shielding systems for complex cable wiring harnesses using conventional heat shrink tubing heating devices. The system offers excellent shielding and significant weight savings over traditional metal braid cable shielding systems. In addition, O-SRINK offers an environmental shield against dust, moisture and other contaminants. O-SRINK remains flexible to support any needed cable routing. asy repair or rework of cables is facilitated by cutting off the O-SRINK material and installing new material. O-SRINK materials are ideal for installation on cabling for medical device electronic assemblies which require reliable MI shielding performance and may benefit from silver s antimicrobial properties. Typical applications can include; missiles, aircraft, satellites, vehicles, and on cables of any other electronics systems where weight savings is mandatory. ontact Information: Parker annifin orporation homerics Division 77 Dragon ourt Woburn, M phone fax chomailbox@parker.com Product eatures Superior MI shielding Meets NS outgassing specs for space use xcellent 360 cable shielding effectiveness performance, db attenuation above 500 Mz Weight savings from 40 65% vs. conventional braided mesh shielding systems with labor savings as well asy installation and assembly with conventional heat guns and ovens Professional appearance xcellent seal against moisture and contaminants omplex cable assembly MI shielding possible with a wide selection of cable transitions, including T, Y, and other custom shapes. Standard (stocked) lengths for tubing are 4 feet. or longer lengths, transition tubing sections are available. Unique coating system can be applied internal or external to the heat shrinkable tubing O-SRINK cable assemblies remain flexible after installation O-SRINK connector boots provide MI shielding, cable shield grounding, and strain relief at connector backshell terminations. O-SRINK boots shrink to a wide range of cable diameters (shrink ratio is 4:1 at the cable end). They can be supplied with a conductive hot melt adhesive/sealant applied to each end. Mil-R Polyolefin Tubing and Boots

2 pplication Instructions One of the major advantages of the O-SRINK MI cable shielding system over conventional metal shielding is its ease of assembly. The following has been prepared as a guide to the proper application and assembly of O-SRINK tubing, connector boots, and transitions. ll O-SRINK products may be recovered (shrunk) with the same heating equipment used on ordinary nonconductive shrinkable plastics. ot air blowers and infrared heating devices provide the simplest method of shrinking. Ovens may be used to recover tubing, but boots, transitions and other molded parts often require some hand positioning during the shrinking process to assure correct alignment. Shrink temperatures should not exceed 375. are should be taken to shrink the product slowly and uniformly. xceeding 375 (191 ) may cause a loss of shielding integrity. To achieve a good mechanical grip between O-SRINK boots and connector backshells, homerics strongly recommends the use of Shrink Boot dapters, which provide a knurled and grooved surface to enhance resistance to torque, snap-off and pull-off stresses. Tie-wraps should also be applied. O-SRINK molded parts are available with a highly conductive hot-melt adhesive/sealant at each opening. This hot melt will flow during shrinking to provide an effective environmental seal without degrading MI shielding characteristics. If excess sealant flows outside the molded part during recovery, it can be easily wiped away while still warm. The only assembly procedure peculiar to O-SRINK is the necessity to maintain electrical continuity through conductive inside surfaces from connector to connector. Where two O-SRINK parts meet (boot/tubing, tubing/transition, etc.), a continuity splice must be achieved. This is accomplished by using O-SRINK splice sleeves, which are short lengths of O-SRINK tubing with a conductive outside surface. or optimal shielding performance, be sure to terminate the shield at both ends with full 360 contact to a low impedance ground. Incorporate mechanical strain relief into the cable design itself. That is, avoid stretching and bending the cable excessively. Transition pieces should be generous to preserve continuity at all junction points. 2

3 O-SRINK ssembly Procedure 1. Lay out entire cable, with all branches in proper place. 2. Slide O-SRINK continuity splice sleeves (coating outside, black inside) into position wherever connector boots or transitions will be shrunk against the cable. 6. Slide O-SRINK transitions into position, bending branches where required to allow the expanded transition to pass breakout intersections. When properly positioned, exposed continuity splices should be entirely covered by the transition. 9. Terminate connector. Note: If connector backshell does not provide a knurled and grooved surface for the O-SRINK boot to grasp, a Shrink Boot dapter should be installed on the backshell before wires are terminated (see table of dapter sizes and part numbers). 3. pply heat to shrink continuity splices tightly against wire bundle. 4. Slide pre-cut lengths of O- SRINK tubing (inside-coated) into position so that ends overlap approximately one-half of each continuity splice sleeve. When determining cut-lengths, allow for a maximum of 5% longitudinal shrinkage. 5. pply heat to shrink tubing against wire bundle. pproximately ½ to 1-1/2 inches of conductive surface should be exposed at each continuity splice. 7. pply heat to shrink transitions in place. During the shrinking process, transitions can be positioned by hand to assure correct alignment and convenient breakout angles. nds of each transition should be pressed down onto the splice sleeve so that the conductive hot melt adhesive around each opening ows around splice to provide a mechanical bond and seal. Note: Do not handle cables after transition shrinkage until cool. 8. If O-SL conductive grommets are to be used to terminate individual wire shields: a. Strip outer jacket o each wire and cut shield away leaving ¼ 3/8 of shield exposed. b. omb exposed shield back over jacket. c. Insert wires into grommet so that exposed shields are securely located in center of grommet. 10. Slide O-SRINK boot over connector, and align so that boot will shrink over threads of backshell (or adapter) at one end and exposed continuity splice at other end. 11. pply heat and begin shrinking boot at connector end rst, using hands to assure proper positioning. Press boot tightly against backshell so that conductive hot melt adhesive provides mechanical bond and seal. ontinue shrinking boot, working from connector towards cable. Press tail end of boot down against exposed splice so that conductive hot melt bonds and seals. 3
